The Briton, who narrowly failed to defend his foil B title on the previous day, taking silver, found his way back to the top of the podium, defeating China’s second seed and Rio 2016 silver medallist Hu Daoliang 15-7 in the final.

The International Wheelchair and Amputee Sports Federation event at the Grand Plaza Cheongju Hotel is a key qualifier for the Tokyo 2020 Paralympic Games.

Coutya's was the second gold for Britain at these Championships following victory in the epee A for Piers Gilliver.

Georgia's defending champion in the sabre B category, Irma Khetsuriani, was seeking gold having lost to Chinese newcomer Shumei Tan at the last World Cup in Warsaw in July – when Tan went on to take gold.

"Sometimes it is necessary to lose, so that you can celebrate new victory with new emotions," Khetsuriani said ahead of the International Wheelchair and Amputee Sports Federation event.

But she was unfortunately knocked out in the quarter-finals, beaten 15-10 by Hungary's Boglarka Mezo.

Meanwhile, Tan moved through for another, more significant gold, beating Mezo 15-6 in the final.

Top seed Zou Xufeng of China edged the women's epee A final 14-13 against compatriot, Bian Jing.

Hungary's world number one and defending champion Zsuzsanna Krajnyak was beaten in the semi-finals, 15-5, by Jing.

The expected challenge of Hong Kong’s Yu Chui Yee ended unexpectedly early in the round-of-16, defeated 15-13 by compatriot Chui Yu.

The final gold of the day in the sabre A was guaranteed to go China, as the last two remaining competitors were Li Hao and Tian Jianquan, who beat Italy's Edoardo Giordan and Gilliver, respectively, in their semi-finals.

Tian took the gold, 15-12.

After two days, China have six golds and Britain two.
